Frequently Asked Questions

What truncation levels are available?

Our tool supports 4 different truncation levels: seconds (preserves full precision), minutes (truncates seconds to 0), hours (truncates minutes and seconds to 0), and days (truncates all to 00:00:00). You can choose the level that best fits your data processing needs.

What's the difference between truncation and rounding?

Truncation always removes precision by setting lower units to zero (e.g., 14:30:45 truncated to minutes becomes 14:30:00), while rounding would move to the nearest value (14:30:45 rounded to minutes might become 14:31:00). Truncation is more conservative and predictable.

Can I use the current time?

Yes! Click the "Use Current Time" button to automatically populate the input field with the current time. This is perfect for quick truncation of the current time to your desired precision level.

What information does the result include?

The result includes the original time, truncated time, truncation level, time difference in seconds, minutes, and hours, truncation details for each component, and comparisons showing all truncation options. This comprehensive analysis helps you understand the truncation impact.

Is there a limit on the number of calculations?

No, there are no limits on the number of time truncation calculations you can perform. The tool runs entirely in your browser, so you can truncate as many times as needed without any restrictions.

Can I copy the results?

Yes! The tool provides a copy button that allows you to copy the truncated results to your clipboard. You can then paste the truncated time into any application or document that supports text input.
